If released, the chemical potential energy will cause the coal atoms and molecules to vibrate violently, and this internal kinetic energy can be transferred to other nearby objects. Which of these is the best way to transform this chemical potential energy into internal kinetic energy? A. burn the coal B. drop the coal from a great height C. roll the coal down a hill D. submerge the coal in water

A. burn the coal

Explanation:

Burning the coal is only the way to convert the stored chemical energy of the coal into the the kinetic energy of its molecules that can then be transferred to the nearby objects in the form of heat by the various modes of heat transfer such as conduction, convection or radiation.

Conduction is the contact method of heat transfer in which the adjacent atom transfers the vibration kinetic energy.

Convection is the bulk mode of heat transfer in which the bulk mass of molecules moves near and far to the heat source.

Radiation is the distant mode of heat transfer in the form of electromagnetic waves.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
